Ottawacity, capital of Canada, located in southeastern Ontario. The central part In the eastern extreme of the city province, Ottawa is located on a limestone bluff situated on the south bank of the Ottawa River across from Gatineau, Quebec, at the confluence of the Ottawa (Outaouais), Gatineau, and Rideau rivers; the northern terminus of the Rideau Canal (which largely follows the course of the Rideau River) is just southwest of that river’s mouth. The city’s climate is continental, with warm, humid summers and cold, usually snowy winters. Ottawa’s metropolitan area lies astride the Ontario-Quebec border and includes (in Quebec) the city of Gatineau. . The Ottawa River (some 790 miles [1,270 km] long), the principal tributary of the St. Lawrence River, was a key factor in the city’s settlement and development; its watershed, covering more than 57,000 square miles (148,000 square km), facilitated the transport of resources such as furs, timber, and minerals from the region. The river’s Chaudière Falls, just west of the Rideau Canal, while initially a navigational hazard for the fur trade and later for the transport of logging rafts, ultimately proved to be an asset in the production of hydroelectric power for the city and a boon to the growth of industry.

Originally a trading and lumbering community that grew into a town of regional significance, Ottawa was named the capital of the Province of Canada in 1857 and retained that status when Canada became a dominion within the British Commonwealth in 1867. Because of its location on the boundary between English-speaking Ontario and French-speaking Quebec and its position as national capital, Ottawa is one of the most bilingual cities in the country. Area city, 1,077 square miles (2,790 square km); Ottawa-Gatineau metro. area,

The earliest inhabitants of the Ottawa region were members of the Algonquin First Nation (Native Americans), who established settlements in the Ottawa River valley. The tribe known as the Ottawa (Outaouais), however, settled in the area for only a short period during the mid-1600s; their traditional territory was considerably farther west on Lake Huron. They were well known as traders (the name Ottawa is believed to be derived from an Algonquian word meaning “to trade”), and they took part in the local fur trade.

The first descriptions of Ottawa’s future site were written in 1613 by the founder of New France, Samuel de Champlain, in 1613. The rivers served as passageways for explorers and fur traders over the following two centuries. In 1763 France ceded all of New France east of the Mississippi River to Great Britain under the Treaty of Paris. The Napoleonic Wars (1792–1815) increased Britain’s need for shipbuilding timber, and the Ottawa River valley offered just such resources. In 1800 an American, Philemon Wright, had begun timbering across the Ottawa River in what became a group of farmers from Massachusetts led by Philemon Wright established the area’s first permanent town, Wrightsville, north of the Ottawa River. (It was incorporated in 1875 as the city of Hull(, now part of Gatineau.) . During the Wright began harvesting trees in 1806, giving rise to a timber trade that attracted lumberjacks and other itinerant workers. Permanent settlement on the south bank of the river did not occur until the following decade, when, during the War of 1812 between Britain and the United States, it became apparent that the Rideau provided the British with a safe shipping route from St. Lawrence River between Montreal and Kingston, Ontario, was vulnerable to attack as both a military and an economic target. The British proposed turning the Rideau River into a canal to serve as an alternate shipping and transportation route, diverting traffic up the Ottawa River to Kingston, on Lake Ontario, thus spurring settlement of Ottawa. It was hastened by the arrival in 1826 of Lieutenant Colonel Chaudière Falls and back down to Kingston. Lieut. Col. John By of the Royal Engineers to work on canalizing the river, and the town became Bytown.Ottawa might still be a modest city had not political quarrels between was in charge of constructing the more than 126-mile- (203-km-) long canal (1826–32). He also surveyed and laid out a town site on the south bank as a place of residence for his workers and himself; that village became known as Bytown. It was incorporated as a town in 1850 and as the city of Ottawa in 1855.

The Rideau Canal was never used as a military route, but its importance in the transportation of timbers, goods, and people was the main factor in the city’s early growth, especially during the period of high U.S. demand for forest products that lasted through the 1800s. Political unrest within Britain’s Canadian colonies (including armed rebellion in 1837) resulted in Britain’s unification of the separate colonies of Upper and Lower Canada into one province, the Province of Canada (1841). When it came time to designate a capital for united Canada, however, political quarrels between rival cities, such as between Quebec city and Toronto and between Montreal and Kingston, induced leaders to call upon Queen Victoria to designate a capital for United Canada. In 1855 Bytown was incorporated and rechristened Ottawa, named for the Ottawa Indians. It became the fastest-growing metropolis in eastern Canada, a development due largely to the presence of the national government. Two major fires, in 1900 and 1916, did considerable damage to the city; the second fire destroyed much of the Parliament Buildings complex. Reconstruction soon began, and the central building was completed in 1922.settle the question. The queen selected Ottawa in late 1857. Although Ottawa was a strong candidate because of its location and its accessibility by rail, the choice still surprised many, given the city’s relatively small size and its identification primarily with the processing and distribution of lumber. When the Dominion of Canada was formed a decade later, Ottawa remained the capital, and it continued to grow as a major administrative centre.

A large portion of Ottawa was razed by a fire in 1900 that destroyed Hull, and in 1916 another fire consumed most of the Parliament Buildings. Reconstruction began soon afterward, and the Centre Block was completed in 1922. The growth of civil service jobs was slow but expanded in response to events such as World War I, the institution of an income tax, the Great Depression of the 1930s, and World War II. Still, the capital city, to all appearances, remained an industrial pulp and paper mill town, with smokestacks and railways dominating the waterfront.

In 1937 Prime Minister William L. Mackenzie King brought the architect Jacques Gréber from France to begin the redevelopment of the national capital district. The plan that was devised included was to “beautify” Ottawa and bring its appearance and amenities more into line with those expected of a capital city. It included the provision of large areas of parkland in and around the federal government buildings and a greenbelt around the city’s perimeter to control urban growth. It also called for the removal of the city. Ottawa’s population continued to grow, reaching some 325,000 in the late 1990s. In 2001 the city merged administratively with its neighbouring communities, more than doubling its population.

The contemporary city

The fur trade and lumbering have diminished in favour of computer-related and other high-technology industries. Tourism and conventions are also major contributors to the economy. The federal government is the major employer. Many commercial and financial associations from around the country as well as embassies and trade associations are also located there.

Ottawa is served by both of Canada’s major railroads and by several airlines. There is a good network of expressways rail lines and industry from the urban centre. With the interruption of World War II, Gréber’s plan was not completed until 1950. Its implementation began through the creation of the National Capital Commission (NCC) by an act of Parliament (1958) and, about the same time, the creation of the National Capital Region, which involved the federal government’s acquisition of some 1,800 square miles (4,700 square km) of land on both the Quebec and the Ontario sides of the Ottawa River. Federal administrative buildings were decentralized, moving to locations on both sides of the river.

The contemporary city

Ottawa’s metropolitan area spans the Ottawa River, including Ottawa on the Ontario side and Gatineau on the Quebec side of the river. The climate is continental, with warm, humid summers and cold, usually snowy winters. Temperatures average in the mid-teens F (about 10 °C) in January and in the low 70s F (about 21 °C) in July.

Ottawa was divided by Lieut. Col. John By in 1827 into two main sections—the Upper Town and the Lower Town—although these are further subdivided into neighbourhoods. The best-known of these in the Upper Town is Parliament Hill, the seat of the Canadian federal government; overlooking the Ottawa River and the canal, the Parliament Buildings comprise three blocks of turreted Gothic Revival granite structures. The most iconic of these, the Centre Block, is home to the House of Commons and features the 300-foot (90-metre) Peace Tower. (The East and West blocks are administrative buildings.) Across the canal from the Parliament is the Château Laurier, a landmark hotel (1912) built in the French Renaissance style. The Lower Town, located east of the Rideau Canal, historically the working-class district, is an ethnically diverse region that includes ByWard Market—the site of the country’s oldest open-air market as well as boutiques, restaurants, art galleries, and pubs—and the Glebe, an upscale neighbourhood popular with diners and shoppers.

The federal government is Ottawa’s major employer. A large number of jobs are also provided by the technology sector; a number of telecommunications, software, defense and security, biotechnology, and wireless companies are located in the capital region. Many commercial and financial associations as well as embassies and trade groups have their headquarters or offices in the city. As the national capital, it is also the site of federal government institutions such as the Bank of Canada, the Royal Canadian Mint, the Supreme Court of Canada, and the Queen’s Printer.

Ottawa is well served by transportation systems, including railroads that provide frequent passenger service, a good network of expressways, and major roads in and around the metropolitan area. There are also an international airport and two regional airports. Regional mass transit is centred on a system of dedicated bus rapid-transit lines (i.e., lines that run on their own roadways) ; in addition, and a light-rail line began operating in 2001. Navigation on the Ottawa and Rideau rivers, except for pleasure craft, is a thing of the past.The major cultural centres remain the city’s three universities. The University of Ottawa (1865) and St. Paul University (1848) are bilingual institutions, whereas instruction at (O-Train). The Capital Pathway, a network of more than 130 miles (220 km) of recreational paths throughout the metropolitan area, serves bicyclists and pedestrians.

Ottawa has many public and private universities, colleges, and professional schools. The leading universities are the University of Ottawa (1848), a bilingual institution, and Carleton University (1942), where instruction is conducted entirely in English. A large community college, Algonquin, provides technical training. Ottawa also houses the National Arts Centre, which The Ottawa campus of Algonquin College (1967) grants degrees and certificates in technical and applied subjects. Cultural institutions include the National Gallery of Canada (a multidisciplinary, bilingual arts centre that includes an opera house and two theatres), the National Library and Public Archives BuildingCanada Science and Technology Museum, the National Museum of Science and Technology, and the National Gallery of Canada.Ottawa contains large tracts of parkland within the city limits, and the National Capital Commission maintains the broad greenbelt around the city as well as the large Gatineau Park in Quebec. The Rideau Canal, now used for recreational purposes, Canadian War Museum, the Diefenbunker (a Cold War museum), the Canada Aviation and Space Museum, and the Bytown Museum. The Canadian Museum of Civilization is across the river in Gatineau. Other attractions include Library and Archives Canada (the national archives), the Parliament Buildings, and Parliament Hill, along with nearby Sparks Street, a designated historic street that was the first outdoor pedestrian mall in Canada.

The Rideau Canal remains a functional canal, though it is used mainly by pleasure craft. It was designated a UNESCO World Heritage site in 2007 in recognition of its unique design and historical significance. In winter the canal freezes and becomes the Rideau Canal Skateway, the world’s longest skating rink. Skating on the canal is a highlight of Ottawa’s Winterlude (each February), a winter-themed celebration presented annually since 1979. Featuring winter sports, music, and snow sculpting, it attracts hundreds of thousands of visitors each year. Other popular annual festivals are Canada Day (July 1) and the Canadian Tulip Festival (May), a celebration originated by the royal family of the Netherlands, who took refuge in Ottawa during World War II and afterward presented the city with a gift of 100,000 tulip bulbs.

Ottawa has many opportunities for outdoor activities in its large tracts of parkland and green spaces as well as in nearby Gatineau Park, an extensive public park on the Quebec side of the Ottawa River. At the professional sports level, Ottawa is home to the Senators of the National Hockey League . The city’s annual Winterlude festival draws large crowds to a variety of cultural events and outdoor activities.and the Rough Riders of the Canadian Football League. Among famous Canadians born in Ottawa are singer Alanis Morissette, actor Dan Aykroyd, and author Margaret Atwood. Photographer Yousuf Karsh did much of his best-known work while based in Ottawa.
